在 HTML 和 CSS 中更改表格中行的颜色

Question

尝试学习 HTML 和 CSS，我有一个简单的问题。

如何为表格中的每一行赋予不同的颜色？例如第 1 行是红色，第 2 行是蓝色等。

这是我的 HTML 代码：

#table {
  font-family: Arial, Helvetica, sans-serif;
  width: 600px;
  border-collapse;
  collapse;
}
#table td,
#table th {
  font-size: 12x;
  border: 1px solid #4D365B;
  padding: 3px 7px 2px 7px;
}
#table th {
  font-size: 14px;
  text-align: left;
  padding-top: px;
  padding-bottom: 4px;
  background-color: #4D365B;
  color: #918CB5;
}
#table td {
  color: #000000;
  background-color: #979BCA;
}

<table id="table">
  <tr>
    <th>Company</th>
    <th>Contact
      <th>Country</th>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
</table>

Answer 1

如果我正确理解了您的问题并且您想为每一行赋予不同的颜色？你有几个选择...

• 为每一行添加一个类并设置它们的样式。
• 使用直接兄弟选择器tr + tr
• 使用:nth-of-type

table tr {background: red;}
table tr:nth-of-type(2) {background: blue;}
table tr:nth-of-type(3) {background: green;}
table tr:nth-of-type(4) {background: yellow;}
table tr:nth-of-type(5) {background: grey;}

<table id="table">
  <tr>
    <th>Company</th>
    <th>Contact
      <th>Country</th>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
</table>

Answer 2

你也可以这样试试

#table tr{background: red;}
#table tr:nth-child(2n+1){background: blue;}

#table {
font-family: Arial, Helvetica, sans-serif;
width:600px;
border-collapse;collapse;

#table td, #table th {
font-size:12x;
border:1px solid #4D365B;
padding: 3px 7px 2px 7px;

#table th {
font-size:14px;
text-align:left;
padding-top:px;
padding-bottom:4px;
background-color:#4D365B;
color:#918CB5;

#table td {
color:#000000;
background-color:#979BCA;
}

<table id="table">
<tr><th> Company</th><th>Contact<th>Country</th></tr>
<tr><td> 1</td><td>2<td> 3</td></tr>
<tr><td> 1</td><td>2<td> 3</td></tr>
<tr><td> 1</td><td>2<td> 3</td></tr>

Answer 3

这可以使用pseudo selectors nth-child 轻松完成。

#table tr:nth-child(odd){background:red}
#table tr:nth-child(even){background:blue}

<table id="table">
<tr><th> Company</th><th>Contact<th>Country</th></tr>
<tr><td> 1</td><td>2<td> 3</td></tr>
<tr><td> 1</td><td>2<td> 3</td></tr>
<tr><td> 1</td><td>2<td> 3</td></tr>
</table>

Answer 4

tr:nth-child(even) {
  background: #ff0101;
}

 tr:nth-child(odd) {
  background: #0030ff;
}

<table class="ex1">

Answer 5

您可以尝试通过 CSS 选择每一行。在你的情况下：

table tr:first-child{background:red}    or   table tr:nth-child(1){background:red}

table tr:nth-child(2){background:blue}

table tr:nth-child(3){background:orange}

table tr:nth-child(4){background:yellow}

table tr:last-child{background:purple} or table tr:nth-child(5)
{background:purple}

Answer 6

下面的一小段代码应该改变颜色表行。

 table, td, th {
    border: 1px solid red;
}

th {
    background-color: red;
    color: black;
}
